Abstract
The invention relates to a stator separating mold which is used for molding a grooved stator sheet and comprises a first template and a second template, wherein a male mold is arranged on the first template; a female mold which is matched with the male mold is arranged on the second template; the male mold is provided with a separating male mold for molding the grooved stator sheet; at least two positioning grooves for positioning the grooved stator sheet are formed around the separating male mold; a separating female mold is arranged on the second template and is corresponding to the first template; and positioning columns corresponding to the positioning grooves are formed around the separating female mold. The invention has the advantages of simple structure, good punching effect and high work efficiency.
Description
Technical field
The present invention relates to a kind of stator splitting die.
Background technology
At present, the motor stator middle part offers the groove that is used to place stator coil, and stator is formed by the silicon steel sheet lamination usually.Therefore, this type of groove just forms when the punching press silicon steel sheet.
In the prior art, " one falls three " mode is adopted in the stator motor punching, after the punching press of silicon steel sheet profile, again with the flute profile punching press.Because profile and flute profile are the branch secondary centre of punch, both concentricitys are difficult to guarantee when carrying out lamination, and the wedging degree of flute profile also is difficult to guarantee, make punching laminate moulding after flute profile uneven, influence motor quality.
Summary of the invention
The invention provides a kind of stator splitting die.
For achieving the above object, the technical solution used in the present invention is:
A kind of stator splitting die, this splitting die is used for the moulding stator lamellar body of jet-bedding, comprise first template and second template, described first template is provided with punch, described second template is provided with the die that is complementary with described punch, described convex mold is useful on the moulding separation punch of the stator lamellar body of jet-bedding, offers at least two and be used to locate the location notch of the stator lamellar body of jet-bedding around described separation punch; Separate die with corresponding being provided with of described first template on described second template, offer and the corresponding reference column of described location notch around the described separation die.
Preferably, described location notch is provided with four.
Further preferably, the opening diameter of described location notch is 8mm.
Preferably, described separation punch ringwise.
Stator splitting die of the present invention is applicable to the stator lamellar body of jet-bedding type, and additional punching press has location hole on the stator lamellar body.Separate carrying out moulding after the stator lamellar body of jet-bedding is located by this location hole, wash away waste part, and obtain final stator lasmination.
Because the technique scheme utilization, the present invention compared with prior art has following advantage: the present invention is simple in structure, and punching press is effective, high efficiency.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
A kind of stator splitting die as shown in Figure 1, 2, this splitting die are used for the moulding stator lamellar body 7 of jet-bedding, and stator lamellar body 7 upper punches have groove 9, are distributed with location hole 8 around groove 9, as shown in Figure 5.This splitting die comprises that first template 1 and second template, 2, the first templates 1 are provided with punch, and second template 2 is provided with the die that is complementary with punch.
Wherein: convex mold is useful on the moulding separation punch 3 of the stator lamellar body 7 of jet-bedding, separates punch 3 and is set to annular; Around separation punch 3, offer at least two and be used to locate the location notch 4 of the stator lamellar body 7 of jet-bedding, in the present embodiment, location hole 8 on the stator lamellar body 7 is provided with 4, so location notch 4 also is provided with 4, and the opening diameter of location notch 4 is set to 8mm.
Separate die 5 with first template, 1 corresponding being provided with on second template 2, separate offering and location notch 4 corresponding reference columns 6 of die 5 all around.
Below the concrete method of operation of present embodiment down of setting forth:
Stator lamellar body 7 as shown in Figure 5 is placed on second template 2, and 4 location holes 8 on the stator lamellar body 7 are set in the reference column 6 of second template 2, as shown in Figure 3.Start first template 1, separate punch 3 inside of groove 9 on the stator lamellar body 7 is washed away, simultaneously the profile of stator lasmination 10 is gone out, as shown in Figure 4.After carrying out 4 punching presses on the same stator lamellar body 7, can go out 4 stator lasminations 10 on every stator lamellar body 7, and produce a stator waste material 11, shown in Fig. 6,7.The location hole 8 that is used for assist location has then been stayed stator waste material 11, can not produce any influence to stator lasmination 10.
Like this, the good concentricity of the stator lasmination of going out by location hole 8 10, the groove 9 behind the lamination is unified neat, the quality of the stator of assurance.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
